Description

Heart-shaped concentric lock

Technical field

The utility model relates to a kind of lock, relate in particular to be used for expressing between a kind of lovers forever care, the concentric lock of never to be separated wish.

Background technology

At present, often express the loyal and steadfast emotion of both sides with concentric lock between lovers, in a single day concentric lock is just locked and can not be opened again, with the lovers that represent to fall in love forever care, never to be separated fine wish.But known concentric lock locking bar is " n " shape, it is heart-shaped having only lock body, the monnolithic case of concentric lock adds heart for " n " shape, monnolithic case and heart greatly differ from each other, and known concentric lock complex structure, as: the disclosed a kind of concentric lock of Chinese patent 200420034918.X, comprise two springs, locking bar has the flange processed complex, and lockhole is the shoulder hole of processing technology difference, and lock body is that the split type connector that needs connects; Chinese patent 200420074247.X also discloses a kind of concentric lock, and its lockpin hole is located at processing technology extreme difference between two lockholes, and is provided with two lock pins and two springs.Baroque concentric lock not only manufacturing procedure is many, is difficult for processing, and manufacturing cost is also high.

The utility model content

Technical problem to be solved in the utility model be to provide a kind of simple in structure, be easy to processing, cost is low, global shape is heart-shaped concentric lock.

The technical solution of the utility model is as follows: a kind of heart-shaped concentric lock, comprise lock body and locking bar, and described locking bar is " M " shape, has the two ends pin that parallels that one is long and the other is short, and lateral wall has groove at the long end of locking bar pin middle part, holds foot portion to be provided with annular groove in this length; It is heart-shaped that described lock body is, its top center formation arc groove that concaves, vertically be provided with the lockhole suitable mutually in lock body top bilateral symmetry with the locking bar diameter, the two lockhole degree of depth equal locking bar two ends pin length respectively, have the lateral trench that connects described arc groove in two lockhole apertures, this lateral trench width is identical with the lockhole diameter; Level has pin-and-hole at the dark lockhole middle part of described lock body, the spring that lock pin is housed in this pin-and-hole and is press-fited by lock pin, and the front end profile of lock pin is suitable mutually with the shape of described annular groove and groove; When the front end of described lock pin inserted groove, locking bar two ends pin all inserted in the lockhole, and the cross bar two ends of this hour locking lever fall into lateral trench, the complete heart of the common formation of cross bar end face and lock body; Distance between described annular groove and groove is greater than the degree of depth of described shallow lockhole, and when the lock pin front end inserted annular groove, the short end pin of described locking bar was positioned at outside the lock body.This kind concentric lock is not only simple in structure, and member is few, and only processes two straight lockhole and pin-and-holes on lock body, and pin-and-hole is sealed up the aperture on the lock body after can being processed as the through hole that connects lock body one end again, and manufacturing procedure is few, low cost of manufacture.

The cross section of annular groove and groove is " ∠ " shape on the described locking bar.Locking bar is convenient to when descending in acclivitous inclined-plane, the lock pin with same inclined-plane is slipped in the locking bar groove, and the downside of groove is the plane, makes lock pin locking bar is locked, can not retreat.

The arc groove height at described lock body top is 1/4～1/2 of a lock body height.Not only make between locking bar and lock body to have the space, also can increase aesthetic feeling, save the manufactured materials of lock body, cost reduces.

When described lock pin front end inserts annular groove, when the short end pin of described locking bar is positioned at outside the lock body, in described shallow lockhole, plug is housed.Unintentionally will pin in the time of so just can preventing from not use, with after the plug taking-up, just concentric lock can be pinned when having only use.

The beneficial effects of the utility model are: simple in structure, be easy to processing, save material, low cost of manufacture; It is heart-shaped that the concentric lock global shape is, the symbolic meaning that has more more attractive in appearance.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1, the utility model is by lock body 1, locking bar 2, lock pin 3 and spring 4 are formed, wherein lock body 1 is that two heart-shaped bodies coincide (as shown in Figure 2), close with symbol lovers two hearty cords, have mutual affinity, the arc groove that oriented indent forms at lock body 1 top, this arc groove height is 1/3 of lock body 1 height, locking bar 2 is " M " shape, have the two ends pin that parallels that one is long and the other is short, portions are provided with the annular groove 2b that cross section is " ∠ " shape at the long end foot of locking bar 2, are provided with the groove 2c that cross section is " ∠ " shape on right sides, locking bar 2 long end pin middle part, the upper side of annular groove 2b and groove 2c can be acclivitous plane, also can be acclivitous cambered surface.Vertically be provided with the lockhole suitable mutually in lock body 1 top bilateral symmetry with locking bar 2 diameters, the two lockhole degree of depth are identical with locking bar 2 two ends pin length respectively, have the lateral trench 2d that connects the concave shaped arc groove in two lockhole apertures, this lateral trench 2d width equals the lockhole diameter, and shape is suitable mutually with the cross bar 2a two ends of locking bar 2.From Fig. 1, can see, level has pin-and-hole at the dark lockhole middle part of described lock body 1, the spring 4 that lock pin 3 is housed in this pin-and-hole and is press-fited by lock pin 3, the front end profile of lock pin 3 is suitable mutually with the shape of described annular groove 2b and groove 2c, when the front end of described lock pin 3 inserts groove 2c, locking bar 2 two ends pin all insert lockhole, the cross bar 2a two ends of locking bar 2 fall into lateral trench 2d, the cross bar 2a end face of this hour locking lever and the complete heart of lock body 1 common formation, it is heart-shaped that the concentric lock global shape is, the symbolic meaning that more is rich in the heart attractive in appearance more.

As shown in Figure 3, distance on the locking bar 2 between annular groove 2b and groove 2c is greater than the degree of depth of lock body 1 shallow lockhole 1a, when lock pin 3 front ends insert annular groove 2b, the short end pin of described locking bar is positioned at outside the lock body 1, this pins preceding structural representation for the utility model, the long end pin of locking bar 2 can rotate in lockhole, but can not withdraw from lockhole, the plug of being made by plastics or rubber 5 is housed in shallow lockhole 1a, plug 5 tops are provided with the flange of being convenient to pull it, unintentionally concentric lock is pinned in the time of so just can preventing from not use, with after plug 5 taking-ups, just concentric lock can be pinned when having only use.

The utility model is to use like this: the plug 5 that will fill in shallow lockhole 1a takes out, locking bar 2 is pressed to lockhole, the long end pin of locking bar 2 continues descending, the lock pin 3 that is stuck among the annular groove 2b is shunk back backward at the effect lower compression spring 4 on inclined-plane, as groove 2c during over against lock pin 3, lock pin 3 is pushed down into groove 2c in the effect of spring force, and locking bar 2 is pinned by lock pin 3, and the cross bar 2a of locking bar 2 is positioned at lock body 1 top and the complete heart of lock body 1 common formation.
